ABSTRACT:
A spread spectrum communication apparatus for communication with a plurality of communication units includes a reception circuit, an automatic gain control circuit, a spread spectrum code detection circuit, and a synthesis circuit. The reception circuit receives signals of a frequency channel inclusive of a target communication unit. The automatic gain control circuit controls the signal intensity of the frequency channel received by the reception circuit to a constant level. The spread spectrum code detection circuit detects the signal intensity of the spread spectrum code of the target communication unit from an output signal of the automatic gain control circuit. The synthesis circuit combines the signal intensity which is based on a gain control signal of the automatic gain control means with a signal intensity as detected by the spread spectrum code detection circuit to find a reception intensity.
